Step by step solution

01

Definition of equilibria

Heterogeneous equilibria is obtained when reactants and products are in separate phases in a chemical reaction, while homogeneous equilibria is obtained when they are in the same phase.

02

Find the system of equilibria for part (a)

a.

The given system is:

\(C{H_4}(g) + C{l_2}\rightleftharpoons C{H_3}CI(g) + HCI(g)\)

Both reactant and product are in same phase, i.e. in the gaseous phase. So, the system is homogenous equilibria.

03

Determine the system of equilibriafor part (b)

b. The given system is:

\({N_2}(g) + {O_2}(g)\rightleftharpoons 2NO(g)\)

Here both reactant and product are in same phase, i.e. in the gaseous phase. So, the system is homogenous equilibria.

04

Detect the system of equilibriafor part (c)

c.

The given system is:

\(2{\rm{S}}{{\rm{O}}_2}(\;{\rm{g}}) + {{\rm{O}}_2}(\;{\rm{g}}) \to 2{\rm{S}}{{\rm{O}}_3}(\;{\rm{g}})\)

Both reactant and product are in same phase, i.e. in the gaseous phase. So, the system is homogenous equilibria.

05

Discover the system of equilibriafor part (d)

d.

The given system is:

\(BaS{O_3}(s)\rightleftharpoons BaO(s) + S{O_2}(g)\)

The phases of reactant and product are different, i.e. solid and gas. So, the system is in heterogeneous equilibrium.

06

Determine the system of equilibriafor part (e)

e.

The given system is:

\({{\rm{P}}_4}(\;{\rm{g}}) + 5{{\rm{O}}_2}(\;{\rm{g}})\rightleftharpoons{{\rm{P}}_4}{{\rm{O}}_{10}}(\;{\rm{S}})\)

The phases of reactant and product are different, i.e. solid and gas. So, the system is in heterogeneous equilibrium.

07

Detect the system of equilibriafor part (f)

f.

The given system is:

\({\rm{B}}{{\rm{r}}_2}(\;{\rm{g}})\rightleftharpoons 2{\rm{Br}}({\rm{g}})\)

Both reactant and product are in same phase, i.e. in the gaseous phase. So, this will give homogenous equilibria.

08

Find the system of equilibriafor part (g)

g.

The given system is as follows:

\({\rm{C}}{{\rm{H}}_4}(\;{\rm{g}}) + 2{{\rm{O}}_2}(\;{\rm{g}})\rightleftharpoons{\rm{C}}{{\rm{O}}_2}(\;{\rm{g}}) + {{\rm{H}}_2}{\rm{O}}({\rm{l}})\)

The phases of reactant and product are different, i.e. solid and gas. So, the system is in heterogeneous equilibrium.

09

Discover the system of equilibriafor part (h)

h.

The given system is:

\({\rm{CuS}}{{\rm{O}}_4}.5{{\rm{H}}_2}{\rm{O}}({\rm{s}})\rightleftharpoons {\rm{CuS}}{{\rm{O}}_4}(\;{\rm{s}}) + 5{{\rm{H}}_2}{\rm{O}}({\rm{l}})\)

The phases of reactant and product are different, i.e. solid and gas. So, the system is in heterogeneous equilibrium.
